  <p>The inline keyword requests that the compiler expand a given
  function in place, as opposed to inserting a call to that function.
  Functions that contain <a href="static.html">static</a> data, loops,
  <a href="switch.html">switch</a> statements, or recursive calls
  cannot be inlined. When a function declaration is included in a class
  declaration, the compiler should try to automatically inline that
  function.</p>
